Hey guys...<br /><br />What would it take to replace the stock exhaust with dual exhaust on my 2001 Chevy Silverado with 4.8L V8? How much are we talking?<br /><br />I don't need any additional power, just more noise. Stupid Idea?

Yea...I just had my truck inspected last week and their damn new computer that talks to Albany wouldn't communicate with my truck!!! Ended up being a fuse. I'll have to check into that. Thanks.

It cost my son $175 to get duals put on his Z71. He already had the stainless bugle horn ends for them. He put straights on it. They just cut the stock muffler off right at the catalytic converter, welded a Y on, bent and welded a couple pipes and viola!! Instant twice pipes!!!!

I just called Monroe and they said there could be a problem with the Vortec engines. Something about too much air flow past the O2 sensor? He wasn't sure about the new NY emissions law either. I don't know...have to do some more research...

Avoid Monroe muffler like the plague. They will rip you off. You can put a cat back system on without a problem. you cannot remove the cats though.

Re: Silverado dual exhaust

My 04 with the 5.3 also has dual cats, right after the downpipes from the headers (manifolds). Would be real easy to just weld up true duals and still have the stock emissions totally intact. <br /><br />Not a dumb idea. I put a Gibson cat-back on my truck, loud and I love it. No problems in 30,000 miles.
